Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rope seat stamping, specifically to a rope seat stamping frock. BACKGROUND

[0002] Rope seat, as its name implies, is a device for fixing ropes. When transporting large, heavy or irregularly shaped goods, it firmly binds the goods on the truck through cooperation with the ropes, preventing the goods from moving, tilting or collapsing due to factors such as vibration, impact or wind pressure during transportation. For example, when transporting goods such as mechanical equipment, building materials and chemical products, rope seats can play an important role in ensuring the stability and safety of goods during transportation.

[0003] Railway freight transportation is an important part of the whole social material transfer, and rope seats are widely used in railway transportation. The rope seat structure of a train truck usually includes a connecting head, a support arm and a rope groove. The production of the rope seat of the train is usually stamping forming. In the prior art, either the stamping node position is bent to form a columnar structure, but the connecting head of the columnar structure has a small connection area with the truck, and the strength after welding is insufficient; secondary stamping is required to form a plate body in the connecting head part; or the whole is stamped to form a plate body structure, but the plate body structure makes the rope groove have edges and corners, which can cut the ropes at the connection with the ropes and need to be chamfered. Therefore, there is a lack of a one-time stamping forming stamping frock. SUMMARY

[0004] The utility model aims at providing a rope seat stamping frock to solve the technical problem that the prior art stamping frock either stamps a columnar structure or stamps a plate body structure, both of which need secondary processing and cannot be one-time segmented stamping formed according to the use requirements of different rope seat structures.

[0005] In order to solve the above problems, the utility model adopts the following technical scheme: a rope seat stamping frock, comprising a base and a connecting plate connected with the punch of a stamping machine, characterized in that: a concave block mold recessed downward is arranged on the base, a convex block mold protruding downward is arranged on the connecting plate, two symmetrical stamping inclined surfaces are arranged in the recess of the concave block mold, an arc-shaped mold is arranged between the stamping inclined surfaces, an arc-shaped pressure-free cavity is arranged on the arc-shaped mold, and the profile of the protruding part of the convex block mold is consistent with the profile of the recessed part of the recessed module.

[0006] The utility model has the advantages that:

[0007] 1. Existing stamping fixtures either stamp the joint to bend it, forming the rope seat into a cylindrical structure, or stamp it as a whole to form a plate structure. The cylindrical structure connector has a small connection area with the truck, resulting in insufficient strength after welding, requiring secondary stamping to form a plate-like connector. Conversely, the plate-like structure from a single stamping results in angular rope grooves, requiring cutting at the rope connection point and chamfering. Both require two processing steps. This application, however, incorporates a stamping ramp in the recessed die. This ramp allows the rope seat connector to be stamped into a plate shape. An arc-shaped die is placed between the ramps to ensure the stamped rope groove forms an arc structure. A pressure-free cavity is provided, allowing the rope groove to enter during stamping without damaging its cylindrical structure. Therefore, a rope seat with both a plate-like connector and a cylindrical rope groove can be stamped in one step.

[0008] Furthermore, a bending point mold is provided between the stamping inclined surface and the arc-shaped mold.

[0009] Furthermore, the protrusion mold includes a beveled punch head, an arc-shaped punch head, and a bending punch point, wherein the bending punch point is the most prominent downward point on the protrusion mold. This ensures that during punching, the support arm position is the first to be stressed, preventing the rope groove from deforming under stress.

[0010] Furthermore, the inclined punch head is provided with a clamping notch, allowing the inclined punch head to better fit the inclined punching surface.

[0011] Furthermore, the bump mold is provided with weight reduction holes.

[0012] Furthermore, the inner wall of the pressure-free cavity has an arc-shaped structure. The arc surface can better fit the cylindrical structure that accommodates the rope seat groove. Attached Figure Description

[0016] The following detailed description illustrates the specific implementation method:

[0017] The reference numerals in the accompanying drawings include: base 1, fixing hole 11, concave mold 2, mold groove 21, stamping bevel 211, arc mold 212, bending point mold 213, pressure-free cavity 214, connecting plate 3, connecting hole 31, protrusion mold 4, mold protrusion 41, bevel stamping head 411, arc stamping head 412, bending stamping point 413, clamping notch 414, and weight reduction hole 42.

[0018] The embodiment is shown in the accompanying drawings Figs. 1-3 The embodiment is shown in the accompanying drawings

[0019] A rope seat stamping tool, including a base 1, which is a plate structure and can be placed on the stamping table of a stamping machine. The base is provided with fixing holes 11 at the corners, which are used to fix the base on the stamping table of the stamping machine by bolts.

[0020] A concave block die 2 is welded at the middle of the base 1. The concave block die 2 is a cubic structure similar to a brick. The middle part is missing some material to form a downwardly concave die groove 21. The die groove 21 includes two opposite stamping slopes 211. An arc-shaped die 212 is arranged between the stamping slopes 211. The arc-shaped die 212 is not directly connected with the stamping slopes 212, but a vertical vertical surface is arranged to form a bending point die 213. The upper end of the bending point die 213 is connected with the arc-shaped die 212, and the lower end is connected with the stamping slopes 211, so that a drop pit is formed between the arc-shaped die 212 and the stamping slopes 211. A pressure-free cavity 214 is arranged at the middle of the arc-shaped die 212. The pressure-free cavity 214 is arranged along the arc of the arc-shaped die 212, so that the cross section is also arc-shaped. The inner wall of the pressure-free cavity 214 is also arc-shaped. The stamping slopes 211, the arc-shaped die 212 and the bending point die 213 are cut to form the die groove 21. After cutting, the pressure-free cavity 214 is opened by a milling cutter.

[0021] The rope seat stamping tool also includes a connecting plate 3, which is mainly used to connect with the punch of the stamping machine. The connecting holes 31 on the connecting plate 3 are fixed with the punch of the stamping machine by bolts.

[0022] A convex block die 4 is welded at the lower end of the connecting plate 3. Two plates are arranged at the upper end of the convex block die 4. The two plates are welded with the connecting plate 3 to form a weight-reducing hole 42.

[0023] The lower end of the convex block die 4 is provided with a die convex head 41 which is consistent with the concave profile of the concave block die 2. The die convex head 41 includes a slope stamping head 411 which is consistent with the inclination angle of the stamping slope 211. The two ends of the slope stamping head 411 are provided with abutting gaps 414. An arc-shaped stamping head 412 is arranged between the slope stamping heads 411. The arc of the arc-shaped stamping head 412 is consistent with the arc-shaped die 212. The slope stamping head 411 and the arc-shaped stamping head 412 are chamfered to form a bending stamping point 413 which is the most downwardly protruding point on the convex block die 4. Therefore, when the stamping machine drives the convex block die 4 downward, the convex block die 4 can be embedded with the concave block die 2 to complete stamping.

[0024] In use, the base 1 is fixed on the punching table of the punching machine through the fixing hole 11, and then the connecting hole 31 of the connecting plate 3 is connected with the punch of the punching machine, so that the installation of the concave block mold 2 and the convex block mold 4 is completed. After the installation is completed, the raw material of the column structure rope base 5 is placed in the concave block mold 2, the punch of the punching machine is driven to move downward, so that the convex block mold 4 moves downward. Since the bending punching point 413 is the most protruding point of the convex block mold, the external force is first applied to the rope base, so that the supporting arm 53 is bent, the rope groove 51 is driven by the supporting arm 53, and the arc-shaped mold 212 is supported, so that the bending is arc-shaped and completely enters the free depositing cavity, so that the deformation under stress is avoided. Finally, under the combined action of the convex block mold 4 and the concave block mold 2, the connecting head 52 of the plate body structure is punched out at one time, and the arc-shaped rope groove 51 of the column structure is reserved. Since the bending point mold 213 is arranged, the gradually changing supporting arm 53 is formed.

[0025] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme known in the art are not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
